In Algeria, there are multiple deficiencies in environmental protection. Today, in the context of the constant evolution of healthcare systems and the growing importance given to environmental preservation, the management of pharmaceutical effluents has become one of the major challenges for the pharmaceutical industry. However, often the interests of companies, especially private ones, do not align with environmental priorities, despite the existence of a range of procedures and legislative mechanisms. This can lead to the creation of safe and sustainable action plans to prevent, reduce, and/or eliminate pollution, harmful effects, and nuisances. Unfortunately, this regulation is widely underestimated and neglected in their actual daily practices and actions. Furthermore, awareness and preventive information on environmental concerns are very limited; regulatory mechanisms are fragmented; safety culture and environmental education are disparate, and monitoring and tracking means are limited. The objective of this work is to assess the environmental impact of the activities of an Algerian pharmaceutical industry in order to reflect on environmental concerns and open national discussions on the harmful effects produced by various companies and the strict application of current regulations. This assessment is based on the evaluation of the value of physico-chemical analysis of sewage discharges from a pharmaceutical industry during manufacturing, research and development processes, as well as waste disposal. The analysis results indicate that the physico-chemical properties of the discharged sewage were within the limits allowed by standards regarding heavy metals. However, the analyses of DOB5, DCO, and the concentration of suspended solids (SS), oils and fats significantly exceed the standardized values. This study aims to raise awareness among stakeholders to implement procedures and legislative measures, potentially leading to the development of safe and sustainable action plans, or even fostering a culture of continuous improvement and lasting prevention.
